EVALUATION METHOD FOR OCCURRENCE AND STRUCTURAL SAFETY OF TUNNEL

摘要

The present invention provides a first modified threshold value input step of receiving a first modified threshold value for a case where precise diagnosis of a tunnel is required; A deformation secondary threshold value input step of receiving a deformation secondary threshold value for a case where there is a risk of tunnel collapse; a measurement value input step of receiving a deformation measurement value from a deformation detection unit installed inside the tunnel; a deformation evaluation step of evaluating whether the measured deformation value is due to long-term deformation or short-term deformation of the tunnel; a stability evaluation step of evaluating whether the tunnel is stable by comparing the measured deformation value with the first deformation threshold value and the deformation secondary threshold value when the deformation measurement value is due to short-term deformation; By presenting a method for evaluating the stability of tunnel structures that to be able to establish
